Covering them is about the only way, they can't be removed without damaging the visor.
I actually had the dinoc at first but one of them wouldn't stay stuck for some reason.
I ended up buying a pair of kids black spandex pants at Wal-Mart for $5, cut the bottom of the legs off, and just slipped them over. They stretched on for a snug fit and no one even notices them. An option for those on a budget!
